A 4.3 magnitude earthquake shook western Colorado and eastern Utah on Wednesday night about 9:45, according to the United States Geological Survey in Golden.
The quake was centered 45 miles east-southeast of Moab and could be felt across Mesa County.
Several people who live on the Redlands called The Daily Sentinel to ask about the quake. Tom Burrows, who lives near the east entrance to Colorado National Monument, said he felt a couple of “sideways nudges” that caused his computer monitor to rock back and forth.
An earthquake in this area is not a usual occurrence but is not unheard of, according to Susan Hoover, a geophysicist at the Golden office. The Paradox Basin, near the Colorado-Utah border, is within the Colorado Plateau and has a low rate of seismic activity.
The last reported seismic activity was a 4.1 magnitude quake in 2004, a 4.3 magnitude quake in 2000 and a 4.6 magnitude quake in 1994, Hoover said.
